HumidAir 11 Water Chamber
The HumidAir 11 Water Chamber for AirSense 11 is a removable accessory specifically designed for use with the ResMed AirSense 11 CPAP device, providing optimal humidification throughout your sleep therapy.
Product Features:
Crafted from durable, medical-grade materials—including injection-moulded plastic, stainless steel, and a silicone seal—the HumidAir 11 Water Chamber ensures a secure fit and consistent performance. It has a maximum water capacity of 380 mL and includes a 90-day warranty.
For best results, always use distilled water. The chamber should be wiped daily with a clean disposable cloth and dried away from direct sunlight to ensure consistent humidification and maintain hygiene during therapy.
Monitor for Wear: If you notice any cracks, leaks, or warping, replace the chamber immediately to prevent damage to your device. The AirSense 11 also allows you to set a recurring notification with the Humidifier Set function to remind you when it’s time to replace the chamber.
Preserve Humidification Quality: Do not use essential oils, perfumes, or other additives, as they can degrade the chamber materials and reduce performance. Always keep the device upright and avoid overfilling to prevent water from entering the tubing or shortening the motor lifespan.
